Center the dropdown icon added to an input with a paired datalist in Chrome (#18511)
This PR tweaks the dropdown arrow added to an input by Chrome when it
has a `list` attribute pointing to a `<datalist>`.

Right now the arrow isn't centered vertically:

<img width="227" height="58" alt="Screenshot 2025-07-14 at 15 41 50"
src="https://github.com/user-attachments/assets/b354a5e8-432d-432d-bfe4-f7b6f6683548"
/>

The cause of this is the line height being inherited into the pseudo
element which controls how the marker is positioned. I *think* this is
because it's being drawn with unicode symbols but I'm not sure. It could
just be from the `list-item` display.

After this PR changes the line height its centered again:

<img width="227" height="58" alt="Screenshot 2025-07-14 at 15 42 05"
src="https://github.com/user-attachments/assets/1afa1f33-cc28-4b1f-9e04-e546f6848f57"
/>

Some notes:

This only affects Chrome and also does not appear to cause issues for
date/time inputs. While weird that this pseudo is the one used for a
`<datalist>` marker it is indeed correct.

Fixes #18499
